centos7防火墙启动失败

Question

centos7中firewalld启动失败

我不知道是不是哪里设置错了，导致使用命令

sudo systemctl start firewalld

无法启动

查看/var/log/firewalld日志显示如下

1. Multiple ebtables programs were executing simultaneously. The ebtables

   used to support concurrent scripts that update the ebtables kernel tables.
2. The kernel doesn't support a certain ebtables extension, consider
   recompiling your kernel or insmod the extension.
